Lightning Talk: Network Tools in FME
April – June 2013
Network, Topology & LRS Tools in FME
Many tools in FME for Topology, Networks and LRS workflows Validating & Cleaning Networks Build Topology Network Analysis LRS operations - Measures
Transformer Categories Network Linear Referencing Geometry Operations
Building a Clean FME Network
Challenge
FME needs clean, fully segmented networks
Complex edges must be split
Segments musttouch
Building a Clean Network
Not Clean – Snapper
Not Intersected – Intersectoror TopologyBuilder
Still not intersected:– PointOnLineOverlayer has a tolerance
Validate a Network Topology
NetworkTopologyCalculator
Finds the connected lines that belong to the same network graph.
Example
Network Analysis
Challenge
Find the valves on pipes near a work site Start with a clean network Split the network into
sub-networks between values Find the sub-network by the
work location Find the values connected to
the sub-network Example
